How to promote a Maschine to Domain Controller on Windows

This is the first part of a complete manual Fail Safe Installation guidance on Windows Server 2008 R2.

In this document I will guide you through the steps with screenshots how you can turn a PC (let it be Virtual or Physical) to a Domain Controller.

1. Install Active Directory Domain Services 'Server Role'
   
   
   
   
   
   
   
   
   
2. Domain Controller Promotion
   
   
   
   In the below picture I used 'at.mordor' as a domain. The other two maschines will be placed into this.

3. After the installation finishes anbd the maschine restart itself. This maschine is ready to serve as a Domain Controller
